To enable the resolution of multiple targets at long ranges and to increase detection sensitivity against low-closing-rate targets, a number of new waveforms have been developed. In this chapter the authors will take up three of these: Range-gated high PRF: Pulse burst: Monopulse doppler. The authors will also briefly consider a new search-while-track mode, which takes advantage of the ESA's extreme beam agility. The authors will introduce to a mode-management software architecture for flexibly allocating the radar's resources and ensuring prompt response to high priority requirements in complex tactical situations.
